I wouldn't be certain about interpreting the "if those parts" to mean you must have multiple standards capacity parts.
Standard cap body with a 10rnd spring and follower plus a roll of duct tape is a combination of parts that will accept more than 10 rounds and very likely feed, even poorly, more than 10.
